In terms of airway management the <strong>2010</strong> AHA Guidelines<br />
for CPR and ECC have a major new Class I recommendation<br />
for adults: use of quantitative waveform capnography for<br />
confirmation and monitoring of endotracheal tube placement.<br />
In addition, the use of supraglottic advanced airways continues<br />
to be supported as an alternative to endotracheal intubation<br />
for airway management during CPR. Finally, the routine<br />
use of cricoid pressure during airway management of patients<br />
in cardiac arrest is no longer recommended.<br />
There are several important changes in the <strong>2010</strong> AHA<br />
Guidelines for CPR and ECC regarding management of<br />
symptomatic arrhythmias. On the basis of new evidence of<br />
safety and potential efficacy, adenosine can now be considered<br />
for the diagnosis and treatment of stable undifferentiated<br />
wide-complex tachycardia when the rhythm is regular and the<br />
QRS waveform is monomorphic. For symptomatic or unstable<br />
bradycardia, intravenous (IV) infusion of chronotropic<br />
agents is now recommended as an equally effective alternative<br />
to external pacing when atropine is ineffective.<br />
For <strong>2010</strong> a new circular AHA ACLS Cardiac Arrest Algorithm<br />
has been introduced as an alternative to the traditional<br />
box-and-line format. Both algorithms represent restructured and<br />
simplified formats that focus on interventions that have the<br />
greatest impact on outcome. To that end, emphasis has been<br />
placed on delivery of high-quality CPR with minimal interruptions<br />
and defibrillation of VF/pulseless VT. Vascular access,<br />
drug delivery, and advanced airway placement, while still<br />
recommended, should not cause significant interruptions in chest<br />
compression or delay shocks. In addition, atropine is no longer<br />
recommended for routine use in the management of pulseless<br />
electrical activity (PEA)/asystole.<br />
Real-time monitoring and optimization of CPR quality<br />
using either mechanical parameters (eg, monitoring of chest<br />
compression rate and depth, adequacy of chest wall relaxation,<br />
length and duration of pauses in compression and<br />
number and depth of ventilations delivered) or, when feasible,<br />
physiologic parameters (partial pressure of end-tidal CO 2<br />
[PETCO 2], arterial pressure during the relaxation phase of<br />
chest compressions, or central venous oxygen saturation<br />
[ScvO 2]) are encouraged. When quantitative waveform capnography<br />
is used for adults, guidelines now include recommendations<br />
for monitoring CPR quality and detecting ROSC<br />
based on PETCO 2 values.<br />
Finally the <strong>2010</strong> AHA Guidelines for CPR and ECC continue<br />
to recognize that ACLS does not end when a patient<br />
achieves ROSC. Guidelines for post–cardiac arrest management<br />
have been significantly expanded (see Part 9) and<br />
now include a new Early Post–Cardiac Arrest Treatment<br />
Algorithm.<br />
Post–Cardiac Arrest Care<br />
The <strong>2010</strong> AHA Guidelines for CPR and ECC recognize the<br />
increased importance of systematic care and advancements in<br />
the multispecialty management of patients following ROSC<br />
and admission to the hospital that can affect neurologically<br />
intact survival. Part 9: “Post–Cardiac Arrest Care” recognizes<br />
the importance of bundled goal-oriented management and<br />

interventions to achieve optimal outcome in victims of<br />
cardiac arrest who are admitted to a hospital following<br />
ROSC. We recommend that a comprehensive, structured,<br />
integrated, multidisciplinary system of care should be implemented<br />
in a consistent manner for the treatment of post–<br />
cardiac arrest patients.<br />
Initial and later key objectives of post–cardiac arrest care<br />
include<br />
● Optimizing cardiopulmonary function and vital organ perfusion<br />
after ROSC<br />
● Transportation to an appropriate hospital or critical-care<br />
unit with a comprehensive post–cardiac arrest treatment<br />
system of care<br />
● Identification and intervention for acute coronary syndromes<br />
(ACS)<br />
● Temperature control to optimize neurologic recovery<br />
● Anticipation, treatment, and prevention of multiple organ<br />
dysfunction<br />
The primary goal of a bundled treatment strategy for the<br />
patient after cardiac arrest includes a consistently applied<br />
comprehensive therapeutic plan delivered in a multidisciplinary<br />
environment leading to the return of normal or<br />
near-normal functional status. Patients with suspected ACS<br />
should be triaged to a facility with reperfusion capabilities<br />
and a multidisciplinary team prepared to monitor patients for<br />
multi-organ dysfunction and initiate appropriate post–cardiac<br />
arrest therapy, including hypothermia. Prognostic assessment<br />
in the setting of hypothermia is changing, and experts<br />
qualified in neurologic assessment in this patient population<br />
and integration of prognostic tools are essential for patients,<br />
caregivers, and families and are reviewed in detail in Part 9.<br />
As a guide to therapy, a new algorithm and a table of<br />
integrated goal therapy care were developed.<br />
Stabilization of the Patient With ACS<br />
The <strong>2010</strong> AHA Guidelines for CPR and ECC recommendations<br />
for the evaluation and management of ACS have been<br />
updated to define the scope of training for healthcare providers<br />
who treat patients with suspected or definite ACS within<br />
the first hours after onset of symptoms. Within this context<br />
several important strategies and components of care are<br />
defined and emphasized by these guidelines and include<br />
systems of care for patients with ST-elevation myocardial<br />
infarction (STEMI), prehospital 12-lead electrocardiograms<br />
(ECGs), triage to hospitals capable of performing percutaneous<br />
coronary intervention (PCI), and comprehensive care for<br />
patients following cardiac arrest with confirmed STEMI or<br />
suspected ACS.<br />
A well-organized approach to STEMI care requires integration<br />
of community, EMS, physician, and hospital resources<br />
in a bundled STEMI system of care. An important<br />
and key component of STEMI systems of care is the<br />
performance of prehospital 12-lead ECGs with transmission<br />
or interpretation by EMS providers and advance notification<br />
of the receiving facility. Use of prehospital 12-lead ECGs has<br />
been recommended by the AHA Guidelines for CPR and ECC<br />
since 2000 and has been documented to reduce time to<br />
